Hi, In a preamp,I like to see ones that are:(1) point to point wired (2)have a external power supply (3)laid out with minimal switches and no tone controls(shorter signal paths and less shit to go to hell)(4)Must be tube(you can tune the sound to your liking by changing tubes,and tube units sound warmer,richer,and more lifelike.)I hope this helps.If not let me know and I can suggest a few of the brands and models I have faith in. The gixerman
Rogue 66; quite nice. A few available here on A'Gon. Check out reviews and Discussion threads.
